Explorer and Mozilla problem - button and font size

The submit buttons are slightly lower than the input field in Explorer 6 Windows.
This is a separate bug.

Explorer (Win and Mac) and Mozilla have weird problems when a
button has a smaller font: the button seems to drop down a bit. The tinier the font,
the more it drops down.

This is the test form:

The first Submit button has 100% font size, the second 80%, the third 60% and the fourth 40%.
Now it ought to look like this:

Sadly, Opera is the only browser that handles this situation correctly. Safari refuses to
use a smaller font than 80% (no screenshot). Explorer Windows and Mac have different problems
regarding to text placement; first Windows, then Mac:

However, Explorer at least keeps the actual buttons in line. Mozilla 1.6 doesn't, not without
a little help:

Firefox 1.0 PR has tried to amend the situation, but it hasn't succeeded:

Solution

The Mozilla problem is solved by giving the inputs a vertical-align of
top, bottom, text-top or middle.
